Anti-roll automobile suspension
First Claim
1. An anti-roll suspension system for a vehicle chassis having at least two laterally spaced front wheels, the suspension comprising:
- an axle assembly for mounting each of a pair of laterally spaced wheels;
a spring assembly for mounting the chassis on each of the axle assemblies;
a pivoting link attached to a lower portion of each side of the chassis;
a moveable control arm connected at an outer end to each axle assembly and at an inner end by one of said links to the chassis; and
a tie link connected between said pivoting links defining an anti-roll linkage structured to translate a lateral force on the chassis during a turn to a downward and lateral counter movement of said chassis toward the up force side (inside of the turn) of the chassis and a vertical upward movement on the down force side (inside of the turn) of the chassis so that the anti-roll linkage simultaneously lifts the down force side of the chassis and lowers the up force side of the chassis to thereby counteract roll of the chassis.

Abstract
An anti-roll suspension for a vehicle chassis is disclosed having laterally spaced wheels, the suspension comprises an axle assembly for rotatably mounting each of a pair of laterally spaced wheels, a spring assembly and a lower control arm supporting the chassis on each of the axle assemblies, a moveable lever connected between the lower control arm and the suspension system being responsive to a lateral force on said chassis to shift the chassis laterally to the up force side of the suspension and to impose a vertical force on the down force side of the chassis so that the anti-roll linkage simultaneously lift the down force side of the chassis and lowers the up force side of the chassis.

12. An anti-roll suspension system for a vehicle chassis having at least two laterally spaced wheels, the suspension comprising:
-
an axle assembly for mounting each of a pair of laterally spaced wheels;
a spring assembly for mounting the chassis on each of the axle assemblies;
a lever attached to a lower portion of each side of the chassis;
a moveable control arm connected at an outer end to each axle assembly and at an inner end by one of said levers to the chassis; and
a tie link connected between said levers, said anti-roll suspension system configured and structured to translate a lateral force on the chassis to a lateral counter movement of said chassis toward the up force side of the wheels and a vertical upward movement on the down force side of the chassis so that the anti-roll linkage simultaneously lifts the down force side of the chassis and lowers the up force side of the chassis to thereby counteract roll of the chassis. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
said double wishbone suspension includes an upper control arm attached to said chassis and a lower control arm attached to said pivoting link; and
said spring assembly is connected to said upper control arm.

20. An anti-roll suspension system for a vehicle chassis having at least two laterally spaced wheels, the suspension comprising:
-
an axle assembly for mounting each of a pair of laterally spaced wheels;
a coil compression spring assembly normally disposed in a substantially vertical orientation for mounting the chassis on each of the axle assemblies;
a lever attached at one end to a lower portion of each side of the chassis, wherein each of said levers is substantially vertically oriented when the suspension is in a static condition;
a moveable lower control arm connected at an outer end to each axle assembly and at an inner end to one of said levers intermediate the ends of each lever;
a tie link connected between the outer ends of said levers, wherein said anti-roll suspension system configured and structured to translate a lateral force on the chassis to a lateral counter movement of said chassis toward the up force side of the wheels and a vertical upward movement on the down force side of the chassis so that the anti-roll linkage simultaneously lifts the down force side of the chassis and lowers the up force side of the chassis to thereby counteract roll of the chassis.
